IMPROVEMENT IN SEWING-MACHINES.

Specification forming part of Letters Patent N o. 186,936, datedFebruary 6, `1877; application filed August 25, 1874.

To all whom it may concern:

` description thereof, reference being had to the accompanying drawings,

making a part of this specification, and to the letters of referencemarked thereon, in which- Figure 1 is a perspective view of a machinemade according to my invention. Fig. 2 is a vertical longitudinalsection of the machine through the shuttle-race; and Fig. 3 is atransverse vertical section of the shuttle and feedholding casing.

My invention has for its object a sewingmachine upon which repairs andother 'sewing upon tubular work may be done with greater facility thancan be done upon the machines now in use; and to this end' my inventionconsists of a machine provided with a brace extending from the leg atone end to that at the other, a part of said brace being provided withbearings in which rotates a driving-shaft, and which brace supports ahollow casing or stand, arranged to contain suitable mechanism foractuating the shuttle and feed; and it also consists of a work-table,having a hole therein, around the vertical casing, into which leaves arefitted and hinged, so that the ver-Y tical casing may be used to placework there on, independent of the work table, or in combination with it,as hereinafter described.

In the drawings, A represents the wooden work-table, supported upon theordinary legs B, and having a strong brace, K, extending from one leg tothe other, and secured firmly thereto beneath the table. Thisbrace isprovided with a bearing at m, in which one end of the driving-shaft Imay rotate, the other end rotating in a bearing in the leg B; and uponthis shaft is a small gear-wheel, F, engaging with the tootheddriving-wheel E, arranged upon a stud projecting from the inside of theleg B; and the wheel E is operated by a pitman connected with thetreadle. The cloth-plate M is upon about the same horizontal plane asthe top of the table, is of circular form, and is supported nponacircular vertical hollow casing, P, which is arranged to contain themechanism to actuate the shuttle and feed; and this mechanism may be arlranged as follows: N represents the shuttlerace, which is just beneaththe cloth plate, and a slot, b, is made in one side of the race, throughwhich is inserted a pin secured to the shuttle.` This pinf, which movesthe shuttle 6, also engages with the upper end of the driving-lever I',pivoted at c, the lower end of said lever engaging with, and operatedby, a

cam, a, upon the driving-shaft I, so that when the shaft is rotated, thedriving-lever I is moved rapidly to and fro, and moving the shuttle e.Upon the shaft I is secured a spurwheel, a, which engages with a similarwheel, n', upon the lower end of the vertical shaft R, which, beingconnected with suitable mechanism at the upper end, operates thefeed-bar, although it may be operated by a piece or a cam attached tothe upper end of the drivinglever I. The shaft I, cam a, driving-leverl, spur-wheel n, vertical shaft R, are entirely covered and inclosedwithin the casings P and P', which protects their working bearings fromthe accumulation of dust and dirt, and prevents soiling the clothes ofthe operator.

This particular arrangement of mechanism for driving the shuttle andfeed I do not claim, however, as it is not an essential feature 'of myinvention, and many other modifications and arrangements ofdriving'meclianism may be used in the same casings P and P', if desired.For this reason the details of construction of the shuttle, feed,needle-arm, and their connections with the lever I and shaft R are i notshown, but will readily suggest themselves to any competent mechanicskilled in the art.

The table A of the machine has an opening, L, entirely around thecloth-plate M and its support P, and two leaves or doors, H, are fittedtherein, and hinged at o, one on each side the cloth-plate, so that whenthese leaves are fastened up, the upper part of the clothplate and tableform nearly an unbroken surface; but if it is desired to sew upontubular work, such as the sleeve of a coat, or the leg of pants, inmaking repairs, the leaves Hare let down, the table and an opening isthereby made in all around the cloth-plate, leaving the lattersubstantially a horizontal plate upon the upper end of a cylinder placedin a vertical position.

By this construction and arrangement of the table, all the ordinaryrepairs of most of the common articles of wearing apparel may be madeupon the machine with the facility and ease which hitherto has not beenpossible with the ordinary machines in use.,

Having described my invention, claim as new is- 1. rj he hollow verticalcasing P, arranged to contain the shuttle and feed mechanism, incombination with the cloth-plate M, and the brace K to support saidcasing, substantially as described. v

what I 2. The hollow casing P, in combination with the brace K, and thetable A, 'having the swinging leaves H, whereby an opening may be leftin the said table all around the said casing, and the latter be usedindependently of the table, and whereby said table may be madecontinuous with the cloth-plate on top of said casing as a support forwork, substantially as described.
